Unable to watch BBC iplayer on TV

Recently when I was trying to watch BBC iplayer I would get the message Internet download failed because size exceeded system memory unit.But now when I go into applications click on BBC iplayer it says iplayer loading and then all I get is a blank screen.I can get BBC iplayer on my Amazon Fire Stick and on my Youview box.The TV is a Sony KDL-42W653A.tHANKS

Different makes of smart TV have different catch up apps. My older LG only has BBC I player and it’s wi fi is poor so for that one I use home plugs . I can use Miracast from my laptop if I want but use a recorder instead, although TV viewing is not very important to me. My kitchen TV is a Samsung with most of the catch up apps. If you have a fire stick surely that turns your TV into a smart one?

Maybe the Sony TV has half the brain of a RASPBERRY PI but the BBC i Player is available on at least two other tech systems you have. What's the issue here? Just live with it as it won't change the world if you have a TV that can't play BBC i Player.
